🎛️ DSP5 Power Level Layout (Typical Example)

Your DSP5 layout can be customized, but a common setup looks like:

DSP5 Position 1 – Stock / Economy

+15–25 RWHP
Best for daily driving, longevity, and fuel economy.

DSP5 Position 2 – Light Tow

+40–60 RWHP
Ideal for towing under ~10,000 lbs with controlled EGTs.

DSP5 Position 3 – Heavy Tow

+60–80 RWHP
Designed for heavy towing (10,000–15,000+ lbs).
Strong mid-range torque with safe heat management.

DSP5 Position 4 – Street Performance

+80–110 RWHP
Responsive throttle and strong acceleration while remaining daily-drivable.

DSP5 Position 5 – Performance / Race

+120–200+ RWHP (mod-dependent)
Maximum power for built trucks and aggressive setups.

Power gains vary based on turbo size, injectors, CP3, and supporting modifications.

Why Piston Twistin EFI Live Tuning Is Different

At Piston Twistin, DSP5 tuning is not just stacked power levels.

Each DSP5 position is:

  • Independently calibrated

  • Built specifically for its purpose

  • Refined using datalog feedback

  • Revised as your setup evolves

Many tuning companies charge extra for:

  • Bigger turbos

  • Larger injectors

  • High-flow or stroker CP3s

  • Additional power levels

  • Hourly tuning support

We don’t.

✅ Our Pricing Philosophy

  • One flat price

  • Any turbo

  • Any injector size

  • Any CP3

  • Unlimited tune revisions included

  • No hourly support fees — ever

You don’t get punished for modifying your truck.

Nice Product and Customer Service
I ordered this BlastIR Wireless Pro IR Repeater from Sewell to replace a wired version of an IR repeater from another company. We have moved our TV on to a wall location and are in the process of hiding all the wiring out of sight behind walls and/or in a cabinet. We still have some wires to go, but this product has enabled us to eliminate the IR wiring all together. It's a real improvement in both looks and performance over the cheaper, wired version we originally tried. The BlasterIR's Receiver is the component that faces the room and receives the IR signal from our remote controls. It's small enough to fit in the space between our sound bar and the bottom of the TV. It's range is great for our room size (about 22' long and 18' wide) and picks up the remotes signal from a side angle that's almost parallel to the TV itself. The receiver is powered through one of the USB ports integrated into the TV (although the device itself supports either a USB or regular plug-in option). I haven't used them yet but Sewell appears to have provided a few options to help with affixing the IR devices in their final positions including some adhesive pads and a magnetic pad option as well. I'm still playing around with the permanent placement of the IR Blaster Emitter. It sits inside a closed cabinet and faces the concealed cable box receiver, router and DVR components. It retransmits the various IR signals it receives from the IR receiver by blasting that signal to anything it faces. I just placed it in the cabinet about 5" away from the devices I wanted to control, plugged it in and it worked with no other set up. So far the BlastIR is working seamlessly and with much better function response time than the cheaper IR version we'd tried at first. The lag time between when a button is pressed on the remote control and the action taking place on the device I'm communicating with is minimal. The emitter itself is plugged into an outlet on a surge protector powering the other in-cabinet devices, although it too could be powered via the provided USB connection if desired. As a note, we did experience a shipping issue during our ordering process. The order it self was processed quickly and shipped in a timely manner. However, there was an issue with our actual receipt of the product and the USPS who reported it delivered to our mailbox when in fact it had not been. Regardless, we reached out to Sewell directly and they quickly resolved the issue for us with no problems and in a timely manner. I would recommend both this IR Blaster Pro product as well as Sewell as a trusted company itself.

Does NOT Transmit Through Walls
Quick and easy setup! Works great within the room. However, will not work effectively between walls (i.e. - AV closet to living room).

Works perfectly - great product
My MBR TV set-up incorporates a cable box set up in a closet about 50 feet from the TV (hung over a fireplace). When it was set up the A/V used a wired infra-red set up that was wired thru the walls, under the floor, into the closet. Unfortunately some mice nibbled on the wiring and it does not work. I have tried everything including the Next Generation extender (over the years bought 6 of them for different TV's) and most recently the Startech. The Next Generation have not been updated in years and over time completely lose their ability to operate. No customer service at all; emails go into a black hole. I had high hopes for the Startech. Easy to set up and worked out of the box. The problem is the lag time. I could live with it when watching live TV, but it was totally impossible when it came to playing back programs from the DVR (which is cloud based). I was losing hope until I tried the Sewell Blaster. Took me less then 5 minutes to set up and it worked instantly. Little or no lag to speak of and I couldn't be happier. NB. Speaking of Sewell, the absolutely BEST way to control your HDMI based TV is the Sewell Direct SW-30062 Dual Band InjectIR sold by Amazon for $55. This is truly plug 'n play and operates with absolutely no lag. Bought 2 of these to operate TV's in my apartment where I had to hide boxes in closets. Well made, great instructions (coordinated with the devices) and I just love this product. I bought mine direct from Sewell ) same price) because I couldn't find them on Amazon when I needed them, but they have a great return policy and I'm told great C/S. If you can't use these then go for the Blaster.

This vacuum is totally worth the extra money! I LOVE MY YELLOW VAC!
Configuration: Vacuum
Don't hesitate to spend a few more dollars on this vacuum, because you won't be sorry over time. I had done extensive research on purchasing my next vacuum when I came across this model. A friend owns one of the dark green limited edition models and had great things to say about it. I tried hers out and that was that. I loved it. She also bought the floor attachment for wood or flat surface flooring that is already included with this model. I loved that attachment when I tried hers out. It glides across the floor and sucks everything up in it’s path. The Calima had everything I wanted in one package and I really loved the cheerful yellow color. The only thing I didn't like was the price of course. However, in this case I do believe you get what you pay for. Luckily, I was able to get an Amazon Warehouse like new Calima with the floor attachment for ever so slightly more than my friend’s vac plus the extra floor attachment would've cost me. YES!!! In my 16 years married life, I have bought and used a Panasonic, a Dyson and most recently a Sears Progressive (discontinued red model). Their life span has been 4-6 years each. I vowed this time to do some research up front, so I can stop my side job of buying new vacuum cleaners. I found I loved canister vacs thanks to the Progressive, so that was my number one priority. Proven longevity was the next priority. When my vac arrived, I immeditely took it out of the box and started vacuuming away. I have family members with allergies and one with allergies and asthma. My old vacuums never did the cleaning job of this little, lightweight yellow sunshine! I enjoy vacuuming again. It is so quiet that every time I use it, my daughter comments on it. It turns on a dime and is so easy to maneuver. The cord is a perfect length and winds up in a snap. I do like the digital features (that can be touched with your toes-no need to bend down) of changing the suction power. I considered other models with the manual dial and even saw one at Bed Bath and Beyond. It wasn't difficult, but the digital is better in my opinion. Compartments open and close with such ease unlike my Progressive, which I had to wrench open every time I needed to change the bag or get an attachment out. I actually broke the clasp off that allows you to change the bag within months of first getting the Progressive. The Progressive and my other vacs for that matter, were all made of cheap plastic. The Miele surpasses all of my other vacs by leaps and bounds! This company makes great vacuums! Thank you Miele and thank you Amazon!

It will change your mind about vacuuming
Configuration: Vacuum
I have Persian carpets, hardwood floors, brick, and tile and this vacuum works well on all of them. I also have short haired dogs and cats and live in the woods so there is a lot to vacuum up here. I have always had Kenmore canister vacuums that lasted forever and I wanted to get a vacuum cleaner that I wouldn't have to replace every few years so spent the extra money to hopefully get what they promise in that regard. I also spent the extra money on this C3 model because it is made in Germany. The body is heavy plastic but lightweight and has a great little rubber bumper around it so it won't mark your walls or break the plastic when you crash into something. The accessories are well made with no strange plastic seams that catch dirt. The hose and tube are made of heavy materials. I have to carry the canister up three different types of stairs including a narrow spiral staircase and it is very easy to do this. The body is slim enough so that it isn't awkward to carry up stairs while holding the hose and tube too. The machine is well designed, something I look for in everything I purchase. It is easy to change speeds, and turn on and off with your foot so you don't have to bend over everytime you want to turn it off or change the speed. The retractable cord is super nice, and something I was used to with the Kenmore. It keeps the cord safe from nicks and also makes it easier to transport and store. A couple of things I miss from my old Kenmore that I didn't get on this model was the on/off switch on the handle, the ability to go from floor to carpet with the beater brush, and 360 degree swivel hose at the attachment to the canister. This machine does come with the parquet twister attachment, which I read from many reviews was a great tool and can agree wholly that it is, and you can certainly leave it on to vacuum your carpets, but the turbo brush which comes with it too, is a much better cleaning tool for low pile rugs. So I vacuum all of my non-carpeted areas first, then switch the tool and go back and vacuum the rugs. It is a bit of a pain but not terrible. The biggest issue is that you have to carry the extra floor tool with you when you climb the stairs holding the vacuum. Again, not really terrible just a bit of a pain. I have had no issues with the turbo brush getting clogged with hair, but then I have short haired pets. I did choose to get the complete mainly because the canister holds the other attachments (crevice, upholstery, and wall brushes) inside making it easy to transport and less likely to lose the tools. The variable speed motor is soooo much quieter than any vacuum I've ever owned. My pets don't freak out when I vacuum now. The turbo tool has a switch on it which allows the suction to be reduced if you are pulling the rug off the floor. There is also a cool little metal strip down the back of the handle to discharge static electricity. You just have to keep your hand on it while you vacuum. This is a good example of thoughtful design. Because I was replacing a nearly defunct vacuum cleaner I was a vacuuming maniac for the first week I had the Miele. My children thought I had lost my mind and wondered how I could possibly be so excited about a vacuum cleaner...it was a change from my focus on other things, like riding bikes and stuff like that. But my house had become a dust bomb and after vacuuming one rug and watching the dull red change to bright red with a beautiful pattern that I guess I had gotten used to not seeing anymore...I started vacuuming everything in sight (that you could vacuum of course). Almost everything returned to its original color and I filled the vacuum cleaner bag quickly. I also love that the bag and filters keep the dust from reentering the house...so you aren't just moving it around to vacuum up again next week. And probably, most of all, even above the excellent job the machine does on removing dirt from carpets and upholstery, cleaning floors (the parquet twister is awesome for getting right up next to the baseboard at weird angles), is the yellow color. How can you not like vacuuming with a bright yellow vacuum?
